What is the reason for occurrence of unequal larvae during chawki rearing?
1. Non maintenance of optimum temperature (27-28C) and relative humidity (85-90%). /_ 2. If the rearing temperature is maintained lower than optimum and if the larvae become physiologically inactive, feeding period prolongs and growth becomes retarded. 3. In extreme cases when the pebrinised eggs are used for rearing the larval appetite reduces and feeds irregularly which results in unequal larvae.
